TTLIFE Reviews 

I HAVE BOUGHT 3 CONCENTRATORS AND AM SATISFIED WITH THEM ALL. DELIVERY WAS QUICK. I HAVEN'T TRIED THE NEW ONE YET, BUT WILL SOON.

The oxygen concentrators that I bought are simple to use and are exactly what I need.

THE product is very good my experience with TTLIFE has been very good delivery is very quick and customer service is great

Not able to work your website very well

Had what was needed-prompt delivery-super low price-easy set up-nice bundle-could not ask for anything more

Machine works fine, the remote control does not work. I tried everything including a new batt. Please send me an answer on what to try , or send me a new one. Thank You

Buyer beware! This company says they will accept returns unopened with full refund, not true.. they give you 60.00 bucks and then donate if you need or if you do want to return you are looking at very expensive shipping fees not worth returning.

I think the machine is well designed and I am finding it useful. My only complaint is the type and level of sound. I can probably adapt but, currently the vibration sound and the pulsing sound make it difficult to read in bed.

I wish I could give NEGATIVE stars. Absolutely horrendous company. Awful product, false advertising, abysmal customer service. STAY AWAY

Hopefully the unit is putting out the correct amount of oxygen as stated. As far as shipment and the company, they were great. Quick shipping and fast delivery.

I haven’t actually turned it on and used it yet, but I just turned it on and it is extremely quiet and it was packaged well and and quick delivery

I ordered the NT-03 portable oxygen concentrator and bought two NT-3 5000mah batteries to keep me running all day. The concentrator came with a 110v charger and a cigarette lighter plug in that worked inside the vehicle and plugged into the oxygen concentrator for continuos use. The concentrator and the two batteries give me 3L of oxygen as a max and it is more than enough for my needs. TTLife was very helpful and went out of their way to make sure I got what I needed. They are a good company and they stand behind and believe in what they sell. I will buy from them again. Thank you

I really didn't expect this kind of quality for the cost. It is a well built machine and worth much more. I can't testify as to its durability as I have only used it for a week however due to its quality I expect many years of use.

Shipping was very fast. The two concentrators I received were of excellent quality. The Instructions were good as well. I highly recommend this company and it's products.

I ordered the wrong machine for my needs. TTLIFE was so helpful in assisting me with the return process and helping me order the correct machine to meet my needs. Thanks so much for your amazing service !

It’s a good product at a reasonable price, communication was good.

I have not yet rec iced my concentrator. When will it arrive. I've been waiting patiently. Thank God I didn't need it yet.

It was easy to complete my order including the checkout portion

Machine is great..best performance over other made to break

There seemed to be a problem with the order. They acted immediately to correct the misunderstandings. The sevice was excellent and product is working fantastically. I would highly recommend doing business with these people. The oxygen concentrator was priced so low I did not expect it to be of such high quality. It is extremely small and quite enough to sit on the bed stand next to my bed with no notable noise. It is as quiet as my CPAP, possibly even quieter. I bought it as a backup for my large condenser which I have had for many years. The old one has been extremely reliable but is huge (about 30 lb.) and so noisy I have had it in the hallway outside my bedroom in order to sleep. I recommend it as a great choice as well as the integrity of the company and excellent service. I have put the old noisy beast away as a backup and am delighted in every way with my new device.
